The GW Instek GPS-2303 is 2 channel, 180W output, linear DC power supply. Overload and reverse polarity protection, and an output on/off switch keep the GPS-2303 and it's load safe from unexpected conditions. A high regulation (0.01%+3mV) and low ripple/noise (<1mVrms, 5Hz~1MHz) are maintained for channel 1 and 2 in constant voltage mode. Automated cooling fan speed control minimizes fan noise according to load conditions, ensuring quiet operation. The GPS2303 Dual Output Linear DC Power Supply is an ideal solution for lightweight, inexpensive bench-top or portable applications requiring high regulation and multiple outputs.
